Hydro initial data generated by SpEC.
This class loads numerical data written out by the SpEC initial data solver. It uses the spec::Exporter
linked in from SpEC to interpolate to arbitrary grid points. The coordinates are assumed to be in SpEC's "grid" frame. We interpolate the following quantities:
The remaining hydro quantities are computed from the interpolated data and the equation of state. The magnetic field is set to zero and the electron fraction is set to a constant read from the input file.
